adults from a certain region asked, "If purchasing a used car made certain upgrades or features more affordable, what would be your preferred luxury upgrade?" The results indicated that

58%

of the females and

51%

of the males answered window tinting. The sample sizes of males and females were not provided. Suppose that of

600

females,

348

reported window tinting as their preferred luxury upgrade of choice, while of

400

males,

204

reported window tinting as their preferred luxury upgrade of choice. Complete parts (a) through (d) below.

a. Is there evidence of a difference between males and females in the proportion who said they prefer window tinting as a luxury upgrade at the

0.05

level of significance?

State the null and alternative hypotheses, where

π1

is the population proportion of females who said they prefer window tinting as a luxury upgrade and

π2

is the population proportion of males who said they prefer window tinting as a luxury upgrade.

Determine the critical value(s) for this test of hypothesis.

The critical value(s) is (are)

negative 1.96 comma 1.96−1.96, 1.96.

(Type integers or decimals. Round to two decimal places as needed. Use a comma to separate answers as needed.)

State the conclusion.

Reject

the null hypothesis. There is

sufficient

evidence to support the claim that there is a difference between males and females in the proportion who said they prefer window tinting as a luxury upgrade.

b. Find the p-value in (a) and interpret its meaning.

The p-value in part (a) is

0.02920.0292.

(Type an integer or a decimal. Round to three decimal places as needed.)

What does the p-value mean?

The p-value is the probability of falsely rejecting the null hypothesis.

Your answer is not correct.

The p-value is the probability of obtaining a result at least as extreme as the one obtained with this sample given that the null hypothesis is true.

This is the correct answer.

The p-value is the probability that the null hypothesis is true.

The p-value is the probability of rejecting the null hypothesis if the test were repeated for different samples.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
